地图 ID 是表示存储在 Google Cloud 中的 Google 地图样式和配置设置的唯一标识符。您可以使用地图 ID 在网站和应用中启用功能或管理地图和设置地图样式。您可以在 Google Cloud 控制台项目的地图管理页面中，为所需的每个平台（JavaScript、Android、iOS 或静态地图）创建地图 ID。

You use map IDs to enable features or manage or style maps on your websites and in your applications. You can create map IDs for each platform you need--JavaScript, Android, iOS, or Static maps--in your Google Cloud console project on the **Map Management** page.\n\nFor more details and features that use map IDs,\nsee [Map ID overview](/maps/documentation/android-sdk/map-ids/mapid-over).\n\nRequired permissions\n\nTo create or manage any map IDs in your project, you\nmust use a principal with the appropriate role-level permissions, Editor or\nOwner, on the Cloud console IAM page for the project. For\ndetails, see\n[IAM basic and predefined roles reference](https://cloud.google.com/iam/docs/understanding-roles#role_types).\n\nCreate map IDs\n\nCreate map IDs in the Cloud console following\nthese steps:\n\n1. Sign in to and open a Cloud console project with the\n [required permissions](#permissions).\n\n2. In the Cloud console, go to the\n [Maps Management page](https://console.cloud.google.com/google/maps-apis/studio/maps).\n\n3. Click **Create map ID**.\n\n4. On the **Create new map ID** page, do the following:\n\n 1. For **Name**, give the map ID a name.\n 2. *Optional* : For **Description**, describe what the map ID is used for.\n 3. For **Map type** , select the platform on which you plan to use the map ID. If you choose JavaScript, also choose a **Raster** (the default) or **Vector** map type. For more information on vector maps, see [Vector Maps](/maps/documentation/javascript/vector-map).\n 4. Click **Save** to show your new map ID.\n\nAssociate a map ID to a map style\n\nIf you are using cloud-based maps styling, you associate a map style with your\nmap ID. For details, see [Associate your style to a map ID](../cloud-customization/map-styles-leg#associate-style-with-map-id).\n\nAdd the map ID to your app \n\nAndroid\n\nAdd your map ID through a `\u003cfragment\u003e` element in the\nactivity's layout file, by using the `MapView` class, or programmatically\nusing the `GoogleMapOptions` class.\n\nFor example, assume you created a map ID that is stored as a\nstring value named `map_id` in `res/values/strings.xml`: \n\n \u003c?xml version=\"1.0\" encoding=\"utf-8\"?\u003e\n \u003cresources\u003e\n \u003cstring name=\"map_id\"\u003e\u003cvar label=\"map_id\" translate=\"no\"\u003eMAP_ID\u003c/var\u003e\u003c/string\u003e\n \u003c/resources\u003e\n\nFor maps added through a `\u003cfragment\u003e` element in the activity's layout file,\nall map fragments that should have the custom style must specify the\nmap ID in the `map:mapId` attribute: \n\n \u003cfragment xmlns:map=\"http://schemas.android.com/apk/res-auto\"\n map:name=\"com.google.android.gms.maps.SupportMapFragment\"\n ...\n map:mapId=\"@string/map_id\" /\u003e\n\nYou can also use the `map:mapId` attribute of the `MapView` class to specify\na map ID: \n\n \u003ccom.google.android.gms.maps.MapView\n xmlns:map=\"http://schemas.android.com/apk/res-auto\"\n ....\n map:mapId=\"@string/map_id\" /\u003e\n\nTo specify a map ID programmatically, pass it to a\n`MapFragment` instance using the `GoogleMapOptions` class: \n\nJava \n\n MapFragment mapFragment = MapFragment.newInstance(\n new GoogleMapOptions()\n .mapId(getResources().getString(R.string.map_id)));\n\nKotlin \n\n val mapFragment = MapFragment.newInstance(\n GoogleMapOptions()\n .mapId(resources.getString(R.string.map_id))\n )\n\nIn Android Studio, build and run your app as you normally would. Custom\nstyles configured in the first step are applied to all maps with\nthe specified map ID.\n\niOS\n\nTo instantiate a map using a map ID, do the following:\n\n1. Create a `GMSMapID` with the map ID string from Cloud console.\n2. Create a `GMSMapView` specifying the map ID you just created.\n\nSwift \n\n let camera = GMSCameraPosition(latitude: 47.0169, longitude: -122.336471, zoom: 12)\n let mapID = GMSMapID(identifier: \"\u003cvar label=\"map_id\" translate=\"no\"\u003eMAP_ID\u003c/var\u003e\")\n let mapView = GMSMapView(frame: .zero, mapID: mapID, camera: camera)\n self.view = mapView\n\nObjective-C \n\n GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:47.0169\n longitude:-122.336471\n zoom:12];\n GMSMapID *mapID = [GMSMapID mapIDWithIdentifier:@\"\u003cvar label=\"map_id\" translate=\"no\"\u003eMAP_ID\u003c/var\u003e\"];\n GMSMapView *mapView = [GMSMapView mapWithFrame:CGRectZero mapID:mapID camera:camera];\n self.view = mapView;\n\nIf you are using your own map ID, you can set your\nmap ID in the Cloud console to have a new style\nat any time, and that style will be reflected on your map view automatically\nfor you and users within about six hours.\n\nIf you want to see the changes immediately, you can close out and restart\nyour app by exiting the app, forcing a quit of the app from the recently-used\napps list, and then reopening it. The updated map will then be visible.\n\nJavaScript\n\nTo create a map with a map ID in your application code:\n\n1. If you are already customizing your map with embedded JSON code, remove\n the\n [`styles` property](/maps/documentation/javascript/reference/map#MapOptions.styles)\n from your `MapOptions` object; otherwise, skip this step.\n\n2. Add a map ID to the map using the `mapId` property. For example:\n\n```javascript\nmap = new google.maps.Map(document.getElementById('map'), {\ncenter: {lat: -34.397, lng: 150.644},\nzoom: 8,\nmapId: '\u003cvar translate=\"no\"\u003eMAP_ID\u003c/var\u003e'\n});\n```\n\nMaps Static\n\nTo add a map ID to a new or existing map that uses one of our\nweb-service APIs, append the `map_id` URL parameter and set it to your\nmap ID. This example shows adding a map ID to\na map using Maps Static API. \n\n \u003cimg src=\"https://maps.googleapis.com/maps/api/staticmap?center=Brooklyn+Bridge,New+York,NY&zoom=13&size=600x300&maptype=roadmap&markers=color:blue%7Clabel:S%7C40.702147,-74.015794&markers=color:green%7Clabel:G%7C40.711614,-74.012318&markers=color:red%7Clabel:C%7C40.718217,-73.998284&key=YOUR_API_KEY&map_id=\u003cvar label=\"map_id\" translate=\"no\"\u003eMAP_ID\u003c/var\u003e&signature=YOUR_SIGNATURE\" /\u003e\n\nIf you have a digital signature in your Maps Static URL before adding your map ID, you will need to [create\nand add a new digital signature](/maps/documentation/maps-static/digital-signature) after adding your map ID. When generating your new URL signing secret, remember to remove your previous digital signature from the URL."]]
